pretty new to the ttb setup. i have a 6in lift on it and now the camber and alignment is going crazy. when i go in reverse the tires toe in drastically. driving forward causes them to toe out. bushings and everything look good. any ideas??"??

My pitman arm has a 4in drop. It would need to be another 3in lower for the linkage to be horizontal and match the pivot points and front axles. Should I just try n find a larger drop pitman or should I change the front linkage? I'm pretty new to the camber and toe issues.
